'Corsham' was a British operation by the Special Operations Executive to protect Follafoss power station and Folden dam to the north of Trondheim in German-occupied Norway (29 January/6 March 1945).

K. Stoltenberg, G. Berg and O. Bergh landed from the sea on 29 January and travelled to their target area. The three men were under orders to work independently, but this proved impossible. Their radios were also damaged and eventually they decided to cross the border into Sweden, arriving in Stockholm on 6 March, and the men later decided not to return to the area.
